A hull is the watertight body of a ship, boat, or flying boat. The hull may open at the top, or it may be fully or partially covered with a deck. Atop the deck may be a deckhouse and other superstructures, such as a funnel, derrick, or mast. The line where the hull meets the water surface is called the waterline.
A hydrofoil is a lifting surface, or foil, that operates in water. They are similar in appearance and purpose to aerofoils used by aeroplanes. Boats that use hydrofoil technology are also simply termed hydrofoils. As a hydrofoil craft gains speed, the hydrofoils lift the boat's hull out of the water, decreasing drag and allowing greater speeds.
Sailing employs the wind—acting on sails, wingsails or kites—to propel a craft on the surface of the water, on ice (iceboat) or on land over a chosen course, which is often part of a larger plan of navigation.
A marina is a dock or basin with moorings and supplies for yachts and small boats. A marina differs from a port in that a marina does not handle large passenger ships or cargo from freighters.
The keel is the bottom-most longitudinal structural element on a vessel. On some sailboats, it may have a hydrodynamic and counterbalancing purpose, as well. As the laying down of the keel is the initial step in the construction of a ship, in British and American shipbuilding traditions the construction is dated from this event.
The Mariel boatlift was a mass emigration of Cubans who traveled from Cuba's Mariel Harbor to the United States between 15 April and 31 October 1980. The term "Marielito" is used to refer to these refugees in both Spanish and English. While the exodus was triggered by a sharp downturn in the Cuban economy, it followed on the heels of generations of Cubans who had emigrated to the United States in the preceding decades.
An outrigger is a projecting structure on a boat, with specific meaning depending on types of vessel. Outriggers may also refer to legs on a wheeled vehicle that are folded out when it needs stabilization, for example on a crane that lifts heavy loads.
A boat lift, ship lift, or lift lock is a machine for transporting boats between water at two different elevations, and is an alternative to the canal lock.
Capsizing or keeling over occurs when a boat or ship is turned on its side or it is upside down in the water. The act of reversing a capsized vessel is called righting.
Hull Marina is a marina for pleasure boats situated in the English city of Kingston upon Hull. It was opened in 1983 on the site of the former Railway Dock and Humber Dock and is managed by British Waterways Marinas Limited (BWML).
A davit is any of various crane-like devices used on a ship for supporting, raising, and lowering equipment such as boats and anchors.
The Philippine Coast Guard (PCG) is recognized as the third armed uniformed service of the country attached to the Philippines' Department of Transportation, tasked primarily with enforcing laws within Philippine waters, conducting maritime security operations, safeguarding life and property at sea, and protecting marine environment and resources; similar to coast guard units around the world. In case of a declaration of war, the Coast Guard shall also serve as an attached service of the Department of National Defense.
Diver rescue, following an accident, is the process of avoiding or limiting further exposure to diving hazards and bringing a diver to a place of safety. A safe place is often a place where the diver cannot drown, such as a boat or dry land, where first aid can be administered and from which professional medical treatment can be sought. In the context of surface supplied diving, the place of safety for a diver with a decompression obligation is often the diving bell.
The Defender-class boat, also called Response Boat – Small (RB-S) and Response Boat – Homeland Security (RB-HS), is a standard boat introduced by the United States Coast Guard in 2002. The boats serve a variety of missions, including search and rescue, port security and law enforcement duties and replaces a variety of smaller non-standard boats.
The Flyak is a hydrofoil adaptation to the conventional kayak. It uses twin hydrofoils designed to raise the hull out of the water to increase the speed. Speeds of up to 27.2 km/h can be achieved on calm water.
The Swedish Coast Guard is a Swedish civilian government agency tasked with:
Lorient Submarine Base was a submarine naval base located in Lorient, France. It was built in 1941 by the German Kriegsmarine, and was continued to be enlarged until 1943. After the German defeat it was used by the French Navy. It was decommissioned in 1995 and converted to civilian use.
Following the September 11 attacks in New York City, many people were unable to leave Lower Manhattan due to the closure of bridges and tunnels and mass transportation.
